Family in Venezuela - how can I find one?

How can I find my family in Venezuela only by their surname?
Google and Ancestry.com couldn't help me so far...

If you're not a Venezuela citizen, try to contact the embassy of your country/nationality and they should put you in the right direction.

I found my polish family and I think this guy can help you in the other direction, you can write and ask him
